> Java Lang implementations of String builders/joiners/concatenation results in a copy. Sometimes, that can be an expensive and memory consuming operation. In those situation, a no/low-copy implementation of CharSequence can helpful. This is often done using a tree/[rope data structure|[https://en.wikipedia.org/wiki/Rope_(data_structure)].]
> Some core features:
>  * no/low copy implementation
>  * optimized tree rebalancing to avoid making the tree too deep
